“This impressive piece of scholarship explores contemporary debates about the nature of expertise and their relationship to politics in novel ways. Eyal writes with verve and a great eye for metaphor, which makes the book a great read.”Harry Collins, Cardiff University “Gil Eyal thinks that the present-day crisis of expertise is substantial and serious but that it has not yet been properly described. His attempt to supply that description is necessary reading for our troubled times.”Steven Shapin, Harvard University
